The body f2 can be used with any number of removable split bushings and the parts are so arranged as to enable the bushing to be quickly and easily inserted or removed.

Also forming an important part of the present invention is the pressure screw 15 which is formed at its upper end with a tool engaging head 16 and this screw extends downwardly through the upper end of the hollow body and the pointed end 17 will pass centrally through the bushing 7 and will engage the outer end of the axle on which the wheel which is to be removed is mounted.

A floating nut 18 is arranged within the reduced upper end portion ot' the bore of the hollow body and thepressure screw is threaded through this nut in the manner clearly shown in Figure l. yI`he upper 'tace of the nut is adapted to engage tbe shoulder 9 formed by the inwardly directed iiange 8, and this is also shown very clearly in Figure 1 of the drawing.

In use, the parts are arranged as shown in Figure 1 with the proper size split bushing seated within the ring-like seat 5. The bushing is then threaded onto the outer threaded end of the hub of the wheel which is to be removed and the head 16 of the pressure screw is rotated so as to move the screw inwardly and as the inner pointed end of the screw is in engagement with the outer end of the axle, and further pressure is applied, the body portion 2 will have a tendency to move outwardly, and the tapered inner face of the seat 5 will cooperate with the tapered outer face of the split bushing to compress the same and tightly secure the bushing on the hub, thus permitting the wheel to be readily and easily moved from the axle.

The simplicity of my device enables the same to be readily and easily assembled 'for use, and will at all times be positive and eliicient in carrying out the purposes Vtor which it is designed. Furthermore, the single body member can be used with various sizes of split bushings, thus saving considerable expense and providing a means whereby the wheel puller can be employed with wheels having diilerent sizes of hubs.

lVhile I have shown the preferred embodiment oit my invention. it is to be un derstood that minor changes in the size, shape, and arrangement oi parts may be re sorted to without departing from the spirit of the invention or the scope of the appended claim.

Having thus described the invention, what I claim is In a wheel puller, a hollow body, the same being formed with a downwardly tapering enlarged annular seat on the open lower end portion of the body, the. upper end ot the body being reduced, an internally threaded split bushing for disposition within the annular seat, the outer peripheral face of the bushing being tapered for cooperation with the tapered seat, said bushing being adapt ed to be threaded on the wheel hub, a pres sure screw extending downwardly through the reduced upper end of the body, the lower end of the screw adapted to engage the outer end of the wheel axle, a nut arranged in the reduced upper end portion of the body through which the pressure screw is threaded, cooperating means between the bushing and the body for limiting the rotary movement of the members with respect to each other in one direction, said means comprising a pair of diametrically opposed lugs extending laterally from the upper edge portion of the bushing, said hollow body being formed with projections with which the lugs cooperate.

In testimony whereof I aix my signature.
